Audio Enhancement TLD100 - Manual (Page 12)

• Plasma television screens generate infrared interference. It is not recommended to use a plasma
display in the same room where the TLD100 is installed.
However, if a plasma screen must be used, install it in the following way and after confirming
operation, use it very carefully.
① Install the infrared sensor in a location where side and back of plasma display cannot be seen, and install it as far
away as possible (more than 10 m {33 feet}).
② The distance between the infrared sensor and microphone should be as short as possible (within 3 m {10 feet})
while in use.
③
④ Do not put any blocks (including the human body) between the infrared sensor and microphone while in use.
Even after following these recommendations, interference may still occur.
• The distance between a fluorescent lamp and the infrared sensor should be as far apart as possible
(more than 1 m {3.3 feet}) in installing.
• If a remote controller such as an audio-visual device or air conditioner is controlled by an infrared
sensor, noise or sound breaks may occur.
• If there are any other devices making strong noises, product may sometimes be impossible to use.
In that case, install the product farther away until it can be used.
• Ceiling height is expected to be 2 m {7 feet} to 4 m {13 feet}. If it is out of this range, the arrival range
may be shortened.
• The base color of wall, floor, and ceiling should be white or light colors. With black or dark color
surfaces, the arrival range may be shortened.
• A reflection from the wall is used in the arrival range. If the wall is far away from the area of use, the
arrival range may be shortened.
• Sound breaks may occur near windows or in rooms with a lot of windows. In this case, it may be
useful to use light-colored curtains or window shades.
• If a microphone is used near and facing a wall, sound breaks may occur.
• For tightening bolts and screws, pay attention to the following points:
① Torque control is necessary for tightening the bolts and screws.
② Torque wrench and torque driver are necessary for controlling the torque.
③ Never use any impact driver or electric drill because torque control is difficult even if they have a clutch. Their use
may result in damage to the mounting part.
• After mounting, confirm visually that the product is firmly and stably fixed. If the product is properly
installed, it will not wobble or make noise.
• In installing this infrared sensor, be aware of the following:
① Be sure that the installation is carried out by qualified personnel when installing at high locations.
② Before installation, confirm that there is nobody around.
③ In order to carry out the installation safely and surely, pay close attention to the safety control.
• The supplied safety strap shall be used.
Be sure to firmly secure the safety strap to the ceiling mount bracket at installation.
• Precaution for installation place and securing of the conversion box:
The conversion box shall be installed on a stable place such as on a shelf and secured with screws as necessary.
• Do not apply strong force to this unit. Failure to observe this may damage this unit.
